## **Notes** 

- (1) DC current that will create a maximum temperature rise of 30 °C when applied at + 25 °C ambient. 

- (2) DC current that will typically reduce the initial inductance by 20 %. 

- **UNGAPPED MODELS:** Highest possible inductance with the lowest DCR and highest Q capability. Beneficial in filter, impedance matching and line coupling devices. 

**GAPPED MODELS:** Capable of handling large amounts of DC current, tighter inductance tolerance with better temperature stability than ungapped models. Beneficial in DC/DC converters or other circuits carrying DC currents or requiring inductance stability over a temperature range.
